Fox’s new Gordon Ramsay reality show MasterChef debuted with the highest numbers for any new series this summer. It posted a 2.7 rating/8 share among adults 18-49, winning the 9PM hour against NBC’s America’s Got Talent (2.1/6) and holding onto 96% of its lead-in. It was a strong Ramsay-themed night for Fox, with Hell’s Kitchen opening at 8 PM to 2.8/10 in 18-49.

Meanwhile, NBC’s Breakthrough with Tony Robbins (0.8/3) at 8PM tied another NBC series, comedy 100 Questions, as the lowest-rated new series launch on any network this summer and on NBC ever. Talent (2.5/7 from 9-11 PM) also posted its lowest rating this summer, down 17% from last week. ABC and CBS aired reruns. Fox easily won the night in the 18-49 demo, with Hell’s Kitchen and MasterChef as the top two programs of the night.
